To all whom it may connerie:

Beit known that l, NxELs ANToN Cenis; TENSEN, residing at Milwaukee,intheeonnty of Milwaukee and State of Wiseonsin, here invented a certainnew and useiil"ut-irtV Valve for Fluid-Compressors, of which thefollowing is e'specioetion, the within ep lieation being divisional ofen application ed y me on September 9, 1899, Serial No. 729,957, for eHigh-Pressure Fluid-Compresser.

My invention pertains to fluid-compressors generally, and moreparticularly to e out-out valve therefor; and its object is to provide avalve of this character more espeoielly designed to he employed inconnection with e. compressor for obtaining high pressures in whichleaks through the euteout valve must be provided against. To devise avalveof this character and having these attributes is the object of thepresent invention.-

In the drawings, Figure 1 is e sectional elevation of s compressor,showing one for'rn oi' apparatus to which my invention ma he applied;Fig. 2, en enlarged sectional elevation of the out-out valve, and Fig. 3e. section on line 3 of Fig. 2.

inasmuch es my present invention is restricted to the eut-out valve of acompressor, I will describe the parts ofthe compressor shown only ingeneral terms, it heine' understoodlthat the compressor illustrated issimply oneV exeuipliiioation of e compressor that may be employed andthat my eut-out. valve is to `he used and applied wherever ap plieebleto perform its functions.

T he compressor-oesinzer 1 has n cylinder 2, in which operates a.single-acting piston Si; The Cylinder has a. heck head or cover 4, oon-Ytaining a discharge-port governdd hy a'disohergefvalve 5 andcommuniruting with the diseherge-pessego As `hown in the sompressorselected For illustreiion purposes only, the disoharyopassage loes 'notooxh4 munieato dirortly u ith the usuel reservoir. but indirof-tlytherewith through n cooling;-

which in the drawings is shown es connected to end forming a part ofthis rernovehle plate 9, which provides en excellent. construction endarrangement of the parts; but of course it will be understood that thisvalve-easing may be separate therefrom. The onlyY require ment is thatsuoli Casin f shell communicate both with the discharge-passage of theoompressor and with the connection Vleading to the reservoir. As shown,this easing eommunieates through a port or passage 11 with the deliveryl end of the oooling-ooill which means that it communicates with thedischarge from the compressor. The easing also communicates with a. pipeor passage 12, leading to the reservoir.

The casing 10 has an open end into which screws e hollowexternally-screw-thresded sleeve 13, which carries the valve proper, 14,seating on s seat 15 when closed.` A central here in the reduced end- 16of this sleeve rev oeives the valve-stein 17, which has e eireulsr2groove i8, es well its the bore, so th et the valve nuev he held inplace by a transverse pin 19.

n e high-pressure compressor more partieulerlv it is imperative that theout-outvalve, device he ell`eetuell \vr sesled effainst leakage whetherthe valve is open or closed, and' to attain this end the valve isoonstruoti ed as Shown in the drawings. The sleeve 13 luis u square orangular hole to receive the :angular end 2() of un operating-stem 21,heviog e handle 22. This operating-stein reciprorutes and rotates in unend oep or heed 23, sri-roving into the casing, and the end 2U has aislight motion or movement horizontally in the sleeve und inde endontthereof. The stem luis screw-ihrem s 24, on which screws alorhingduimlle 25, hearing against the cap Bil, so :is to reeipromitethe stein 31 in one dil l l i l l i s l rvolion or the other through itsseid slight independent movement. When suoli stein is ifm-iprocutmloutwurcl hy means of the looking-hundir, un enlurgeuwnt or eollur .26 ismused to sont tightly against the inner end 27 ol' thil und cup.Consequentlyen); pres sure looking' into the (fhuiuhor in which the stemmul 2li situutvd is prevented from raping to the elmosphere.'lheconstruction shown l-oostii otrs liolh u locking devise end u. soull'or the uboot valve. lt is obvious that when the vulve 14 is sented hyturning IOO the handle it may be locked. in closed position iiysubscqucntl y turning the lockinghandle 2.5, so that the valve cannot beopened without l'irst unlocking it by rotating the handle 25. At thesame time when the valve 14. was locked on its seat the rotation of thehandle 25 caused the operating-stem 21 to be drawn outward, so that itscollar 26 was caused to seat u on the seat 27, thereby securely sealingt ie entire valve device and preventing any leakage whatever. Thesecut-out valves are adapted to be used in oonnection with any compressorand are parti ouiarly useful in a con'ipressor having a plurah ity ofcornpressor-cylinders and a plurality of delivery pipes or passages, sothat one of the compressors may for any reason be out out of connectionwith the other or active compressors. The normal position of thevalve114 is open, so as to permit free eonnnunication between the pipeor passage 11 and the pipe or passage 12, communicating with thereservoir.

Although I have described more or less precise forms and details olconstruction, I do not intend to be understood asilimiting myselfthereto, as I contemplate changes in form, the proportion of parts, andthe substitution of equivalents as circumstances may Suggest orrender'expedient and without de? parting from the spirit of myinvention.
